Description
Technical field
The present invention relates to a kind of serial fan, relate in particular to a kind of easily assembledly and, can effectively reduce the serial fan of the phase mutual interference between a plurality of fans simultaneously in conjunction with firmly.
Because axial flow fan has characteristic simple in structure, with low cost and that air quantity is bigger, thus extensively used as various sinks, as the radiation fan in the computer system.
Be generally the fault of avoiding because of axial flow fan and cause operation interrupted, can on former sink, series connection one overlap standby fan usually, interrupt causing overheated suffering damage because of fan running to avoid system or device.
Background technique
And so-called tandem fan is with two designs of fan by structure and circuit of self contained function separately, it can and be stored in the independent fan frame, and become the fan of a monomer.As shown in Figure 1, traditional tandem fan is respectively motor 11 and movable vane portion 12 to be assembled in the first fan frame 13 successively, another motor 14 and another movable vane portion 15 are assembled in the second fan frame 16 in regular turn, two fans assemble respectively finish after, by screw two fans are given combination again, this design is comparatively complicated and need more time of cost and higher creation cost in assembling.
In addition, in existing tandem fan product, generally be that two independent fans simply are together in series, therefore must regard it as two independently fans.Simultaneously, after two simple series connection of fan, its blast may not necessarily produce the effect of addition, reduces running efficiency each other because this series connection may increase impedance each other.For example, as shown in Figure 1, when air-flow through a plurality of ribs 131 in two fan frames 13,16 and 161 o'clock, not only can not strengthen blast, can produce flow-disturbing on the contrary, make the radiating efficiency of fan reduce.Therefore, as desire minimizing interference each other, the distance between two tandem fans certainly will be elongated.Yet under the installing space condition of limited, this mode is also infeasible.
